Megalodon - Robin Brown

When a nuclear submarine is destroyed and evidence points to the Megalodon, an immense, supposedly extinct, prehistoric shark, Frank Acremann of the Institute of Marine Studies seeks a solution to the problem.

MEGALODON ANCIENT ANCESTOR OF THE SHARK. OVER 200 FEET IN LENGTH WITH RAZOR-SHARP 24-INCH TEETH. OMNIVOROUS. NOW EXTINCT.
The news stuns the scientific community, the Pentagon and the White House: MEGALODON still lives. Somewhere deep in the waters of the North Pacific there lurks something monstrous, immense, primeval.

The Jules Verne, a nuclear sub surveying the gold-rich floor of the Mo-lokai Fracture, returns to the surface a bro-ken, battered hulk. The one clue to its ruin is the shard of a tooth some say could be-long only to an immense, prehistoric shark that has long been thought extinct—the MEGALODON.

Terror mounts as a diving bell and yet an-other sub vanish into the eerie darkness of the ocean's depths. Bewildered Navy ex-perts turn finally to the Institute of Marine Studies and Frank Acreman, its brilliant di-rector, a pioneer in the study of the intelli-gence of marine creatures. Acreman sets out for the project site with a team of trained dolphins and a seemingly impossible plan. A gargantuan struggle begins, one that will pit a giant sperm whale, Acreman's dolphins, and the Navy against a haunting specter out of dim prehistory.
